Using antiques for modern milk handling (Alfa-Laval Cream separator)

[Guest guest]

Hiya folks, just a few weeks away from getting our first milking cow

and we've been sourcing some antiques for handling the milk. Which has

led me to a few questions... (p.s. in New Zealand)

We've found an old Alfa-Laval cream separator in excellent condition.

Question 1 - the bowl where you put the milk in appears to either be

tin or aluminium (highly doubt stainless steel). Any idea how to tell

what metal it is? If aluminium I'm totally against it, but are there

negative health (or flavour) effects of tin? From what I could tell

from the instruction book, some of the parts are definitely tin, even

if the bowl isn't). I can send a picture if anyone is familiar with

the models.

Question 2 - I'll only have a maximum of 2 milking cows... is hand

skimming as easy and feasible as it sounds -- I'm thinking the machine

is overkill!?

Also found a great mint condition butter churn made in NZ likely from

white pine, circular style. Immaculately clean, no borers.

Question 3 - should I have any concerns? (aside from tired arms!)

Thanks! Fresh, raw milk here I come!
